    IGNY8 Unified API Standard v1.0
    
    A comprehensive REST API for content planning, creation, and management.
    
    ## Features
    - **Unified Response Format**: All endpoints return consistent JSON structure
    - **Layered Authorization**: Authentication → Tenant Access → Role → Site/Sector
    - **Centralized Error Handling**: All errors wrapped in unified format
    - **Scoped Rate Limiting**: Different limits for different operation types
    - **Tenant Isolation**: All resources scoped by account/site/sector
    - **Request Tracking**: Every request has a unique ID for debugging
    
    ## Authentication
    All endpoints require JWT Bearer token authentication except:
    - `GET /api/v1/system/ping/` - Health check endpoint
    - `POST /api/v1/auth/login/` - User login
    - `POST /api/v1/auth/register/` - User registration
    - `GET /api/v1/auth/plans/` - List subscription plans
    - `GET /api/v1/auth/industries/` - List industries
    - `GET /api/v1/system/status/` - System status
    
    Include token in Authorization header:
    ```
    Authorization: Bearer <your_access_token>
    ```
    
    ## Response Format
    All successful responses follow this format:
    ```json
    {
      "success": true,
      "data": {...},
      "message": "Optional success message",
      "request_id": "uuid"
    }
    ```
    
    All error responses follow this format:
    ```json
    {
      "success": false,
      "error": "Error message",
      "errors": {
        "field_name": ["Field-specific errors"]
      },
      "request_id": "uuid"
    }
    ```
    
    ## Rate Limiting
    Rate limits are scoped by operation type. Check response headers:
    - `X-Throttle-Limit`: Maximum requests allowed
    - `X-Throttle-Remaining`: Remaining requests in current window
    - `X-Throttle-Reset`: Time when limit resets (Unix timestamp)
    
    ## Pagination
    List endpoints support pagination with query parameters:
    - `page`: Page number (default: 1)
    - `page_size`: Items per page (default: 10, max: 100)
    
    Paginated responses include:
    ```json
    {
      "success": true,
      "count": 100,
      "next": "http://api.igny8.com/api/v1/endpoint/?page=2",
      "previous": null,
      "results": [...]
